#    MIB Table/Group Maker
#
#	This is a file designed to create an input file for nroff,
#	includable in a MIB document by putting a line of the form
#
#	.so mibTableFile
#
#	into the boilerplate file.  This works on the principle of
#	conservation of boilerplate.
#
#	input variables:
#
#	$document	The document being instrumented
#	$mib		The name of the nroff input file
#	$group		The page heading text
t="Table"
e="Entry"
g="Group"

By convention, a table or group has an identifying header that
is part of every object name inside it, like the IP Group
contains the ipNetToMediaTable and the ipRouteTable, and the
ipRouteTable specifies the ipRouteEntry and in turn the
ipRouteNextHop.  The base name for the IP Group is 'ip', and
the base name for the ipRouteTable is 'ipRoute'.
